Production of submicron-size monodisperse polymer particles having aldehyde groups by seeded aldol condensation polymerization 总被引:2,自引:0,他引:2
Submicron-size monodisperse polystyrene/polyglutaraldehyde composite particles having aldehyde groups at the surfaces were produced by seeded aldol condensation polymerization of glutaraldehyde in the presence of polystyrene particles prepared by emulsifier-free emulsion polymerization. This technique is expected to be useful for the production of size-controlled polymer particles having aldehyde groups.Part CXXXVI of the series Studies on Suspension and Emulsion 相似文献

For the assessment of a public impact caused by radionuclides released from nuclear facilities, a dynamic compartment model
was developed for prediction of behavior of radioiodine in air, paddy field and rice plant system. The transfer coefficients
among compartments were determined by some experimental data and assumptions for each chemical form of iodine. A verification
of the model was carried out by some case studies. 相似文献

Alternating and random copolymers of 9-phenanthrylmethyl methacrylate or 2-(9-carbazolyl)ethyl methacrylate with styrene were synthesized and their fluorescence properties were examined. There was no noticeable difference in the spectral features of the alternating and random copolymers in tetrahydrofuran (THF), demonstrating that this type of polymers have no quenching sites in the polymer chains. The fluorescence quenching studies indicated that the alternating copolymers permitted singlet-state energy migration as efficiently as the corresponding random copolymers but less efficiently than the random copolymers with higher chromophore contents. These results strongly suggest that to be chromophores close to each other is most important for facilitation of an intramolecular energy migration. © 1995 John Wiley & Sons, Inc. 相似文献

A novel diselenide was synthesized in good yield via only four steps from phenol, and was employed as the catalyst for the Baeyer-Villiger oxidation with 30% H2O2 to obtain lactones in good yields. 相似文献
